SPECIFICATION forming part of Letters Patent No. 290,240, dated December 18, 1883.

Application filed April 14, 1883. (No model.)

To aZZ whom it may concern/.-

Be it known that we, ANDREW FREDERICK JoHNsoN, a subject of the King of Sweden and Norway, who has declared his intention of becoming a citizen of the United States, and is a resident of Stillwater, in the county of Washington and State of Minnesota, and JOHN P. TURNER, a citizen of the United States, and residing at St. Peter, Nicollet county, Minnesota, have invented certain new and useful Improvements in Combined Bag- Filling and XVeighing Machines, of which the following specification is a full, clear, and exact description, reference being also had to the accompanying drawings.

This invention relates to an apparatus for weighing grain, seeds, meal, &c., but more especially designed to be used in connection with thrashing-machines, for the purpose of weighing off in sacks the grain thrashed; and it consists in the construction and the arrangement of parts hereinafter shown and described, and then sought to be specifically defined by the claims.

In the drawings, Figure 1 represents a front elevation, partly in section. Fig. 2 repre sents a side elevation; and Fig. 3 represents a plan view with top and platforms and the central hollow post in crosssection, to show the arrangement of scale-balances.

F designates the foot or base on which a hollow post, P, is erected. To the top of this post is fixed a two-spouted top or cap, T T provided with a rocking valve, V, upon a rock-shaft, X, and adapted to fit beneath a spout, S, and be connected thereto by hooks e 6 so that the grain falling from the spout will run into which of the spouts T T the valve V is set to guide it.

L L are two horizontal platforms a short distance above the base-frame F, and having upright backs N N parallel with and in close proximity to opposite sides of the central post, P. Upon these platforms bags D D are placed, the mouths of the bags being held-by hooks H around the outsides ofthe lower ends of the spouts T T, as shown.

B B are two right-angled metal bars running across beneath the platforms L L upward between the backs N N and central hollow post, P, and pivoted by their upper ends at b I) to the elbows of two bell-crank arms, B B. These bars 13 B" are securely fastened to the platforms L L and backs N N", and are provided with downwardly-projecting arms a a which are adapted to rest against grooved anti-friction pulleys 1% R mounted in the base F, as shown, while the upright parts of the bars rest against similar grooved anti-friction pulleys, It R, mounted upon the oppositesides of the post P. By this means the platforms L L backs N A, and bars 13 B may be raised and lowered to alimited extent between the antifriction rollers with the expenditure of very little power. The two bell-crank arms 13 B are pivoted at E E in slots in the upper part of the post P, with their inner ends overlapping each other inside the hollow post, and connected together by a chain, 0 passing downward around a chain-pulley, I. The outer ends of the bellcrank project in an upward and outward direction through slots in the spouts T T", and are connected to opposite sides of the valve V by chains 0 and G, and the upper ends of the bars B B, as before stated, are pivoted to the bell-crank arms at their elbows.

Suspended from the pulley P are weights W IV V W, corresponding to the amount of grain to be run into either of the bags D or D, as hereinafter shown.

The operation of this device is very simple, and will be readily understood from the drawings.

The weights XV IV IV V correspond with the kind of grain to be weighed, and the amount each sack D or D is to hold being varied according to circumstances, wheat requiring one set of weights, oats another set, barley another set, and so on. The apparatus having been set beneath the spout S, and the proper set of weights having been determined upon, they are placed in position, as shown in Fig. 1.

The front of the hollow post P is provided with a door, M, adapted to be locked at M, to

prevent the weights being tampered with, and after the proper weights are arranged in position this door is closed and locked. The aacks D D are then suspended from the spouts The spout S in the drawings represents the discharge-spout of a thrashing-machine to which the device is especially applicable; but it may be used for sacking and weighing grain in connection with elevators, mills, warehouses, or in any other place where grain is to be handled.

In the drawings the sack D has just been filled and has overbalanced the adjusted weights V \V \V \V and caused the bar B to pull down the short arm of the bell-crank B, and, through the chain 0, thrown the valve V over, so as to turn the grain into the other spout, T, and sack D. Then the sack D is removed and tied up and an empty one hung in its place upon the spout T before the sack D is filled. Then when a sufficient quantity of grain has run into the sack D to overbalance the weights the falling of the platform L and bar B will throw the valve V over and shoot the grain into the empty sack on the platform L, and so on, filling the sacks alternately and weighing them automatically.

The friction-pulleys B B B B permit the platforms to be run up and down with the expenditure of very little force. These antifriction pulleys, as shown, will be grooved, so that they will act as guides to the bars B B at the same time that they act as anti-friction rollers, and thus cause the platforms to move up and down perpendicularly.

Small plates (1 (P will be arranged upon the short arms of the bell-crank levers B B where -they pass through the slots in the spouts to \Ve claim- 1. The combination of two alternately rising and falling receptacle-holding platforms, levers from which the said platforms are suspended, a chain or cord connecting the opposite arms of the said levers, and a weight or weights suspended from the said chain or cord, substantially as and for the purpose herein specified.

2. The combination of the platforms L L having the right-angled bars B B, base F, having central support, 1?, mounted thereon, bell-crank levers B B, oppositely-branching spouts T T having valve'V, chains 0 0, connecting said valve with said crank-arms, chain 0 pulley P, and weights W V V substantially as and for the purpose specified.

3. The combination of the platforms L L backs N N, bars B B", base F. central support, P, anti-friction pulleys R It B R, crankarms B B, chain C", pulley P, and weights suspended from said pulley, substantially as specified.

4. The combination of two alternately rising and falling platforms holding the grainreceptacles, lovers from which the said platforms are suspended, a chain or cord connecting the opposite ends of the said lovers. a weight or weights suspended from the said chain or cord, branching spouts leading to the respective grain receptacles, a valve alternately closing the said spouts, chains or their equivalent connecting the said levers and valve, and a registering device actuated by the said valve, all substantially as herein specified.

In testimony whereof we have hereunto set our hands in presence of two subscribing wit nesses.
